Hi I am working on angular 5.I want to disable click event of mat-list-item want to enable only click action of mat-icon.
<mat-nav-list>
<mat-list-item
*ngFor="
let item of (speciality_list | listFilter: { name: searchText })
"
[class.disabled]="!item.status"
[ngClass]="item.id == specialityActiveId ? 'active' : ''"
(click)="onRowClick(item, 'speciality')"
>
<div matLine>
<div fxLayout="row">
<div fxFlex="80">{{ item.name }}</div>
<div fxFlex="12" >
<button class="cursor-default"
mat-icon-button
(click)="edit($event, 'speciality', item)"
>
<mat-icon class="mat-17">edit</mat-icon>
</button>
</div>
<div fxFlex="8">
<button mat-icon-button mat-icon-button>
<mat-icon class="mat-17">arrow_forward_ios</mat-icon>
</button>
</div>
</div>
</div>
</mat-list-item>
</mat-nav-list>
Thank you,
You can stop immediate propagation by doing this:
edit(event){
event.preventDefault();
// EDIT: Looks like you also have to include Event#stopImmediatePropagation as well
event.stopImmediatePropagation();
}
I referred to the following link for my solution.

The problem is that after 5 seconds, though the value of the variable changes, the alert is still visible.
I checked some similiar questions, and have seen this happening when bootstrap's javascript wasnt loaded. But for me, Bootstrap v5.0.1 JS is being loaded from the CDN and appears in the sources tab in Chrome.
Try to change the function inside of setTimeout to arrow function like this
setTimeout(() => { // code here })
The this inside of setTimeout(function () => {}) reference to the wrong context (the function itself) instead of the Vue component.
The arrow function doesn't have the this binding so when you use the arrow function the this keyword will reference the Vue component and change the state.

I want to add validation to a modal window, I need a behavior in which when the OK button (form submission) is clicked, validation would take place, and if the result is negative, the window should not close
my modal
<b-modal
size="lg"
id="modalToRepair"
title="Add Problem"
title-class="font-18"
centered
body-class="p-4"
no-close-on-backdrop
no-close-on-esc
#ok="onClickModalRepair"
>
<div class="row">
<div class="col-lg-12">
<div class="form-group row">
<label class="col-4 col-form-label">
Repair Problem
<span class="text-danger">*</span>
</label>
<div class="col-8">
<input
v-model="theProblem"
type="text"
class="form-control"
placeholder="Input problem"
name="theProblem"
:class="{
'is-invalid': typesubmit && $v.theProblem.$error
}"
/>
<div
v-if="typesubmit && $v.theProblem.$error"
class="invalid-feedback"
>
<span v-if="!$v.theProblem.required">Requred field.</span>
</div>
</div>
</div>
</div>
</div>
</b-modal>
and my methods
Vue.js
methods: {
onClickModalRepair() {
this.typesubmit = true;
this.$v.$touch();
if (this.$v.$invalid) {
this.$bvModal.show("modalToRepair"); // not work - modal hide
//code for not hide this modal
return;
}
}
},
validations: {
theProblem: {
required
}
}
is it possible?
The method used in the #ok event, is passed an event, which you can call .preventDefault() on, if you want to prevent the modal from closing.
onClickModalRepair(bvModalEvt) {
this.typesubmit = true;
this.$v.$touch();
if (this.$v.$invalid) {
bvModalEvt.preventDefault();
return;
}
}
You can see an example of this on the docs.
I'm trying to focus on several elements of my form but the first one, despite being applied, returns an error by console.
This is my template:
<div class="container">
<div class="col-xs-12">
<div class="row">
<h1 class="animal-title">Your selection is : </h1>
</div>
<div class="wrapper">
<form class="first-form" #submit.prevent="onSubmit">
<div class="image-wrapper">
<div class="sel-image">
<div v-on:click="imageSelected = true" v-for="item in items" v-bind:key="item.id">
<label>
<input
type="radio"
name="selectedItem"
ref="item"
:value="item.id"
v-model="itemFormInfo.selectedItem"
#change="onChangeItem($event)"
/>
<img v-if="item.id === 1" src="../../assets/1.png" />
<img v-if="item.id === 2" src="../../assets/2.png" />
<img v-if="item.id === 3" src="../../assets/3.png" />
</label>
<p class="cie-animal-subtitle">{{item.name}}</p>
</div>
</div>
</div>
<div class="form-select">
<div v-show="filteredStock && (imageSelected || itemFormInfo.selectedItem) > 0">
<h1 v-if="this.itemName === 'Phone' || this.itemName === 'Tablet'" for="selectedItem" ref="itemVisible">
Select the brand of your <span>{{this.itemName}}</span> :
</h1>
<h1 v-if="this.itemName === 'PC'" for="selectedBreed" ref="itemVisible">
Select the type of your <span>{{this.itemName}}</span> :
</h1>
<select
ref="brand"
class="form-control"
id="selectedBrand"
v-model="itemFormInfo.selectedBrand"
#change="onChangeBrand($event)">
<option v-for="brand in filteredBrand" v-bind:key="brand.name">{{ brand.name }}</option>
</select>
<div v-show="this.isBrandSelected">
<h1>What are you going to use your
<span>{{itemName}}</span> for ?
</h1>
<input
type="text"
id="componentName"
ref="componentName"
class="form-control fields"
style="text-transform: capitalize"
v-model="itemFormInfo.component"
#keypress="formChange($event)"
/>
<div class="loader-spinner" v-if="loading">
<app-loader/>
</div>
</div>
</div>
</div>
<div class="service-options" v-show="isComponentCompleted">
<div class="from-group">
<h1>
Here are the options for your <span>{{this.itemFormInfo.component}}</span> :

<div class="services">
<div class="column-service" v-for="option in options" v-bind:key="option.name">
<div class="service-name">{{option.name}}</div>
<div class="service-price">{{option.price.toString().replace(".", ",")}} </div>
</div>
</div>
and here my first method
onChangeItem(event) {
let item = event.target._value;
this.itemName = this.getItemName(item);
if (this.isItemSelected = true) {
this.isItemSelected = false;
this.isComponentCompleted = false;
this.isLoaderFinished = false;
this.itemFormInfo.name = ""
}
this.$refs.item.focus();
},
in this function that I control my first input, the focus is working but it returns me by console the following error:
"this.$refs.item.focus is not a function at VueComponent.onChangeItem"
I have seen some references to similar cases where they involved the reference in a setTimeout or used the this.$nextTick(() => method but it didn't work in my case.
What am I doing wrong?
How can I focus on the next select with ref brand, once I have chosen the value of the first input?
Thank you all for your time and help in advance
How can I focus on the next select with ref brand, once I have chosen the value of the first input?
You want to put focus on brand but your onChangeItem handler is calling this.$refs.item.focus() (trying to focus item). Seems strange to me...
Reason for the error is you are using ref inside v-for.
Docs: When used on elements/components with v-for, the registered reference will be an Array containing DOM nodes or component instances
So the correct way for accessing item ref will be this.$refs.item[index].focus().
Just be aware that right now v-for refs do not guarantee the same order as your source Array - you can find some workarounds in the issue discussion...
I am new to vue I have component which if the endpoint fails, calls my generic 'Error' modal. All this is working fine but I keep getting the following error:

This only happens for the else part of my method function.

I've tried using v-if before and I also had similar problems and the best solution I found was, instead of using v-if/v-else-if/v-else, use v-show instead to perform conditional rendering.
Also, as the Vue.js doc says:
Generally speaking, v-if has higher toggle costs while v-show has higher initial render costs. So prefer v-show if you need to toggle something very often, and prefer v-if if the condition is unlikely to change at runtime.
When I click the button on my modal with an empty field on my input its give me an undefined value on my console. And when I put a value on my input and click the button it is adding to my database. The problem is even the empty field or the undefined value are also adding to my database and the sweetalert is not working. I want to prevent the empty field adding to my database and prevent the undefined. Can somebody help me?

The easiest way to stop this is adding data check. And condition check at top of your method.category_description !== undefined. Btw, move your e.preventDefault() to top too.
First of all do this:
- <button type="submit" #click="category_description !== undefined ? addCategory : ''" class="btn btn-primary"> Add Category </button>
+ <button type="submit" #click.prevent="addCategory" class="btn btn-primary"> Add Category </button>
and then in addCategory:
addCategory() {
if (!this.category_description) {
return;
} else {
// do your stuff here
}
}
When you are clicking on Add Category button, it is triggering the addCategory along with your validation method.
The return value of validation method has no impact on triggering of addCategory.
This issue can be handled in following ways.
Call addCategory only when there is some valid data
<button type="submit" #click="category_description != undefined ? addCategory() : ''" class="btn btn-primary"> Add Category </button>
Call the validation method inside addCategory and then proceed.
